Connecting 48 Vdc Power For Poe Operation - Enterasys MATRIX 7H4385-49 Hardware Installation Manual

Connecting 48 Vdc Power for PoE Operation

Connecting 48 Vdc Power for PoE Operation

The Matrix N5 (7C105‐P) chassis provides 48 Vdc to connected PDs (powered devices) by
way of its backplane connection to a PoE‐compliant DFE module such as the 7H4385‐49.
For a Matrix E7, (6C107), Matrix N1 (7C111), Matrix N3 (7C103) and Matrix N7 (7C107)
chassis, an optional external Enterasys Matrix N‐POE Power System is required to
support PD connections to the 7H4385‐49. The power from the Matrix N‐POE Power
System is supplied through a DC power cable connection to the front‐panel 48 Vdc
Optional Power connector on the 7H4385‐49.
Refer to the Matrix N‐Series N‐POE Power System Installation Guide to install and connect a
Matrix N‐POE Power System to the 7H4385‐49.
3-14 Installation
Note: When you install the 7H4382-49 in a Matrix N5 chassis
Optional Power Input does not support a connection from an external N-POE Power
System. The 48 Vdc power is supplied through the backplane of the N5 chassis from its
own 48 Vdc power modules. If none of these power modules are installed, then there is no
PoE support.
Warning: The DFE module is shipped with a cover over its 48 Vdc Optional Power Input
connector. Do not remove this cover when the DFE module is installed in an N5 chassis.
This cover is removed only when you connect a 48 Vdc power cable from the Enterasys
N-POE Power System.
Advertencia: El modulo DFE es embarcado con una cubierta sobre su conector de poder
opcional de 48 Vdc. No remover esta cubierta cuando el modulo DFE es instalado en un
chassis N5. Esta cubierta debe removerse unicamente cuando se conecta el cable de
poder de 48 Vdc hacia el Sistema de Enterasys de Energia por Cable (Enterasys N-POE
Power System).
Warnhinweis: Im Auslieferungszustand der DFE Module stülpt eine Schutzkappe über
dem 48V Gleichspannungs-Anschluss, die nur dann abgezogen werden darf, wenn ein
Enterasys N-POE Power System angeschlossen wird. Keinesfalls darf diese Schutzkappe
abgezogen werden, wenn das DFE Modul in einem N5 Chassis installiert wird.
Warning: The 48 V wire harness contains two fuses, F11 and F29. If a fuse needs to be
replaced, it must be done by service personnel only. The fuse must be replaced with the
same Type and Rated fuse 20 A, 400 VDC.
Advertencia: E arnes del cable de 48V contiene dos fusibles, F11 y F29. Si un fusible
requiere ser reemplazado, debe ser hecho por personal de servicio unicamente. El fusible
debe ser reemplazado por uno del mismo tipo y clasificado como fusible de 20 A,
400 VDC.
Warnhinweis: Im Kabelbaum der 48V Zuleitung befinden sich 2 Sicherungen, F11 und
F29. Die Sicherung darf nur duch Fachpersonal getauscht werden und darf auch nur
durch den gleichen Typ ersetzt werden ( 20A / 400VDC ).
Note: If you are planning to install a PoE-compliant DFE module such as the 7H4385-49
in a Matrix N3 (7C103) or Matrix N7 (7C107) chassis, install and connect the Matrix
N-POE Power System before connecting to PDs.
